Log message:
Add an extra byte to the end of struct pcb and make sure that it is set to
0xff.  Intel (vol1 section 9.5.2) says that there must be a byte inside the
TSS after the iomap because it always reads two bytes when checking
permissions for io accesses.  before this, bits 1016-1023 were ignored.

This means that the entire pcb_iomap (and i386_*_ioperm) are accurate;
pr#1190 fixed
